TMCC switch not responding

Dick MalonOGR Forum Member

I have an 048 TMCC Fast Track switch that suddenly decided not to respond to TMCC commands. The lantern lights up, the switch operates smoothly manually, and the non-derailing feature works fine. But if I press the programming button to attempt to reprogram the switch the lantern doesn't flash and the switch doesn't respond to resetting the switch number.

Has anyone had experience repairing a TMCC switch? I'm thinking the motor driver must be OK since the non-derailing feature works so it must be a TMCC receiver. The parts list shows a PCB Receiver. Does that sound like the right repair part?

Thanks.

It’s 691 FTSW 01B

There some things you might try first like TMCC signal strength by the switch, etc

The switch worked fine until about a week ago. Another one about a foot away works fine. FWIW I have been having a number of problems with Fast Track switches. I had one that jammed and I couldn't move it. Took it apart and found the problem. I ordered parts and repaired it. Now I have another one that jams about every 4th time I operate it-at least this one I can jiggle a little and it will release and operate again. I do not look forward to taking my track apart to get the switches out let alone having to repair them.

FWIW, I've replaced the push-button in a few of these, the cheap button doesn't hold up. You have to find the type with the longer stem that projects up higher than the standard ones of this type.

A friend of mine ordered some of the receivers during the parts sale. I asked him why and basically said they stopped working.
